Open toolWhat these encoding tools cover
Encoding is a translation, not encryption, and these tools keep that distinction clear. Turn text into Base64 or back, escape a URL or a chunk of HTML, translate between binary, decimal and hex, or convert to Morse code and Roman numerals for teaching and puzzles. Unicode is handled properly, so emoji and non-Latin scripts survive the round trip.
Common jobs
- Embedding an image or a token as Base64
- Escaping a query string before it goes into a URL
- Decoding a JWT payload to see what it claims
Why they run on your device
These pages are static files. The work is done by JavaScript in your tab, so a file or a password never leaves your machine — there is no upload endpoint on this site to send it to. That also means no account, no usage counter and no queue.
Questions
Is Base64 secure?
No. It is reversible encoding, not encryption. Anyone can decode it, so never use it to hide a secret.
Does it handle emoji?
Yes. The tools encode UTF-8 properly, so emoji and non-Latin text decode back unchanged.
